standby and a couple small changes

[caggles]

• Added an option to spin up a standby to recover to a new cluster if necessary. If you enable it and deploy, it'll spin up a standby cluster from the listed repo and recover data from the most recent backup. Then you just disable it to promote the cluster to primary from standby. This serves as an easy way to recover the database from disaster.
• Recommend that the route option is disabled by default. It's probably a better idea for people to turn it on if they want it, rather than expecting people to remember to turn it off if they don't.
• Updated a small typo in bucketName.
• I assume the S3 incr backup schedule was supposed to be 1 hour off the local incr backup schedule, but it was matched up at midnight before, so I fixed that.
